How to Edit MP4 Video in Mac/Windows (Windows 8 included)

MP4 is a very common media format that can keep high image and sound quality. Many downloaded movies, streaming music videos, or recorded video clips are with .MP4 file extension.

If you have many such files, chances are that you need to edit MP4 videos.

How to Easily Edit MP4 Video:

1. Cut MP4 Video

To cut your MP4 video in to certain parts, drag and drop the video on the Timeline and highlight it. Then place the red Time Indicator to where you want to cut the video, and click the Scissor button above the timeline. After that, move the red marker to the end of the scene, and repeat this again to cut the video into several fragments. If you want to cut off the unwanted parts, right click the video and choose "Delete".

2. Join MP4 Video

To join several MP4 video files into one, you just need to place all the video files on the timeline, adjust the order and hit "Create" to export it.

If you want to make the joined videos look like a really intact movie, just add transitions between clips for smooth change from one to next. To do this, click "Transition" tab on the main screen. Then drag the effect you like to the timeline to apply. If you don't want to choose the transition one by one, let the software choose the transition randomly by right clicking and selecting "Random to All" option.

3. Edit the audio of MP4 Video

Sometimes you may need to adjust the settings of audio. To do it, double click the video on the Timeline. Then a editing panel will pop up. Switch to Audio column and you can easy change the Speed, Volume, Pitch of the audio file or add the Fade in/out effect to it.

Want to change the original audio track of your MP4 video? No problem. Just highlight your MP4 video, right click and choose "Audio Detach". The audio file of your video will immediately be separated and appear on the music timeline. Since it is separated from the video, you can easily delete the audio track or replace it with your own music.
